foiltex – A LaTeX2ε class for overhead transparencies

This is a ven­er­a­ble pack­age, which used to have many ad­mir­ers. It
has not, how­ever, been adopted by any of those de­vel­op­ing
screen-pro­jec­tor pack­ages (as for ex­am­ple
sem­i­nar was adopted by the de­vel­op­ers
of pros­per).

The class may be used with fan­cy­box
to place a va­ri­ety of bor­ders around the slides.
